Specification of Letters Patent.

Patented Aug. ii, 1914.

Application led July 15, 1913. Serial No. 779,221.

ToraZZ whom 'it may concern Be it known that I, CHARLES STUART FACKENTHALL, a citizen of the United States,

residing at Pacic Grove, in the county off Monterey, State of California, have invented a new and useful Filter, of which the fol-v lowing is a specification.

`My invention relates to improvements in; filters such as are commonly employed inr removing impurities from water, wine and other liquids. f Y

The objects -of my improvements are:

First, to provide a filter ofthis class whichis adapted to remove impurities from the.V

liquid passing through it and Whichis prof vided with means whereby these impuritiesV may be carried off after being removed froml the liquid by the filter; second, to provide af device of this character which may be readily taken apart for inspection or re-j newal of the ltering element; third, to provide such a filter in a form that will be ornamental and more ecient than previous de` vices of this character; fourth, to provide al filter that can be readilyadjusted to meet varying degrees of-pressure; and fifth, to

provide a filter that can be readily adapted to meet the requirements of iiuids of varying degrees of density.

FurtherV objects and advantages will ap-E pear hereinafter.

Referring to the drawings which are for. illustrative purposes only: Figure 1 is anI elevation of my invention, portions *thereof being shown in section. Fig. 2 is a sectional plan view on the lines 2--2vof Fig.` 1 looking in the direction of the arrows. Fig. 3 is a sectional plan view on the lines ac3- m3 of Fig. 1 looking in the direction of the arrows: Fig. 4 is a perspective view of one member of the filter. Fig. 5 is a perspective view of other members of the lter shown in a dis-l assembled position. y j

In the embodiment of my invention illus-` trated in these drawings, 1 is a body member provided with a thread 2, at the lower end thereof for'attachment to the supply pipe not shown which furnishes the liquid to be filtered. This body member 1 has an inlet opening 3 extending longitudinally therethrough, and an outlet opening 4 eXtending downwardly therethrough as illustrated in Fig. 1. 5 is a bib of any of the well known forms provided with a valve stein 6, operated by a handle 7 the stein 6 extending downwardly into the body' of the bib and ac'tuatA body 19 is secured and seats.

ing the valve therein, whereby the supply of liquid may be controlled. The upper portion of the body 1 is provided with a thread 8 upon which is carried a frame 9, this frame being provided with a glass cylinder l0, which'seats upon a washer 12, the frame being cut away as shown at 13, so that the eX- Vternal surface of the glass 10 is exposed. The upper portion of the frame 9 is provided with a thread 14 upon which is fastened a clamping nut 15, this nut being used for the purpose of securely seating a top 16 against a washer 121 which seats upon the glass 10. The top 16 is provided with a threaded nipple 17 anda washer 18 upon which a valve This valve body 19 is provided with a valve stem 20 and a handle 21, the valve stem 2O extending into the body member 19, and actuating a valve therein so that the flow of liquid in a goose neck 22 may be controlled. Extending downwardly from the top 16 is a flange 23 into which is threaded a cylinder 24, this cylinder being provided with an enlarged portion 25 intermediate of its length upon which is threaded a clamping ring 26. The cylinder 24 `has a recess therein, the upper portion of which recess is provided with a shoulder 27,1ipon which is seated a washer 28. A metal cartridge, consisting of a shell 29 and a wire gauze member30 crimped therein, is filled with a filtering material 3l. The lower edge of the cartridge 29 is crimped back to form a shoulder 32, as shown in Fig. l and Fig. 5. The lower portion of the clamping ring 26 is filled with a body of filtering material 33, which is retained in place by a wire gauze member 34. The ltering material 33 is forced against the flanges 32 of the cartridge 29 and the upper edge of the cartridge 29 is Aforced against the washer 28, which is seated on the shoulder 27, this forcing action being accomplished by setting up "upon the clamping ring 26. `An annular space 35 is thus provided between the cylinder 24 and the clamping ring 26, as shown in Fig. 1.

The method of operation of my invention is as follows: The liquid to be filtered is admitted into the lower portion of the glass 10 through the opening 3. This liquid may be drawn oif through the filtering material 31 Y and 33 and through the goose neck 2,2, by"

any" Solid impufiaes, which 'mai/ibi@ @Onftained therein, separated therefrom, and

'emerges from the' goose neck 22 in a ltered" condition. The bib 5 is provided for drawwith'drawrthroughf opening 4l. The stream of unfiltered water when forced upwardly through the opening 3V impinges upon the;V

-filtering material andrwashes Voff the imvpurities deposited on the surface thereof.' These `impurities Vare carried away in' the stream of unfiltered Water which fio-ws Y I .Y .through the bib.

Infilters in which a body of filtering material, such as felt, is clamped inside aV metal .container or cartridge, it is extremely diffi-V cult to prevent a seepage offunfiltered fluid along the surface of the containing member vbetween it andthe body of filtering material.` This seepage tends toforce the filtering maf yterial away V`from the wall of the .cartridge and to let unltered fiuidthrough. One of .the objects of my invention is toV prevent this flow of unfilteredfiuid between the body of filtering materialand the metal surface of the'cartridge in which it is inclosed. .Y It

will be noted that I have pro-,vided armetal cartridge, consisting of a shell 29, andthat l this cartridge ispaclred witha filtering materiall. It will also be noted that the ends of-this ,cartridge are turned up at 32 and that` they are. pressed firmly againstf the body of-filtering material, which is Vcarried in the clamping ring" 26.k YThis tends to prevent the seepage vmentioned between the .filtering material'l and the shellV 29. The chamber plays an' important part in the 'operation of this filter.V4 Oncethis chamber is filled with the liquid bein'g filtered, there is' no further vmovementjin the confinedliquid, hence no further intrusion Of-unfiltered huid, and consequently. no possible leakage of unfiltered liquid into the filtering media or between-the -ltering v'media andthe metal., Because of this trap the fluid pass- ,ing through the filter .deposits upon 'the Vlowersurface of the lter all rejectedsolids, .andthe solids; so deposited are acted upon "and movedby a jet-of water directed against the underside; of this-filteringY material throughthe openingj f The i filter i as lillustrated is articularly adapted for filtering water, the ltering maand a fine granular substance.i A' filter of this same construction can be used for filter .terial used in this case being preferably felt ingrwine'and other liquids omitting the body of filtering material Blfand depending lupon' the flteringmaterial' entirely, It is obvious that felt, chamois or otherrmaterial may be used in this connection( While thefilter as illustrated isjcommor'ilymade V,of
